Stormwater pollution from residual chlorine after outdoor disinfection with sodium hypochlorite is an increasing environmental challenge due to its potential negative impact on aquatic ecosystems. Even at low concentrations, residual chlorine can disrupt the stability of water ecosystems. In this regard, stormwater treatment requires innovative and green solutions such as green infrastructure (rain gardens) using the plant phytoremediation technique to reduce the amount of residual chlorine. This study explores the interactions between residual chlorine retained by plants in a rain garden and different microelements. Selected plants were analyzed via spectroscopy, and possible interactions with elements such as chlorine (Cl), phosphorus (P), zinc (Zn), iron (Fe), calcium (Ca), potassium (K), nickel (Ni), silicon (Si), manganese (Mn), magnesium (Mg), chromium (Cr), and cadmium (Cd) were determined using Python-based analysis. Chlorine presented significant positive correlations with cadmium (0.39-0.53) and potassium (0.51-0.55), while negative correlations were found between silicon and chlorine (-0.48--0.54) and chlorine and iron (-0.45--0.51). The correlations between chlorine and microelements suggest both common uptake mechanisms and mutual interactions. These results provide a better understanding of the behavior of chlorine in rain gardens and its interactions with other materials, which is especially valuable for designing green infrastructure. This research can help to develop sustainable solutions that reduce environmental pollution and strengthen urban adaptation to climate change.
用次氯酸钠进行户外消毒后，雨水受到余氯污染成为一个日益严峻的环境挑战，因为它可能对水生生态系统产生负面影响。即使浓度很低，余氯也会破坏水生态系统的稳定性。在这方面，雨水处理需要创新的绿色解决方案，比如利用植物植物修复技术的绿色基础设施（雨水花园）来减少余氯量。本研究探讨了雨水花园中植物留存的余氯与不同微量元素之间的相互作用。通过光谱分析对选定的植物进行了分析，并使用基于Python的分析方法确定了与氯（Cl）、磷（P）、锌（Zn）、铁（Fe）、钙（Ca）、钾（K）、镍（Ni）、硅（Si）、锰（Mn）、镁（Mg）、铬（Cr）和镉（Cd）等元素可能存在的相互作用。氯与镉（0.39 - 0.53）和钾（0.51 - 0.55）呈现出显著的正相关，而硅与氯（-0.48 - -0.54）以及氯与铁（-0.45 - -0.51）之间存在负相关。氯与微量元素之间的相关性表明了共同的吸收机制和相互作用。这些结果有助于更好地理解氯在雨水花园中的行为及其与其他物质的相互作用，这对于设计绿色基础设施尤为重要。这项研究有助于开发可持续的解决方案，减少环境污染并加强城市对气候变化的适应能力。
